<p>[QUOTE=&quot;oval_man, post: 2722906, member: 22602&quot;]This is their explanation of their process in general and doesn&#039;t refer specifically to + grades. I don&#039;t think anyone really knows what CAC does with plusses. I&#039;ve raised this question before on CT and have gotten no response. I&#039;ve never called CAC or talked to a dealer about it.</p><p><br /></p><p>Personally, what I believe CAC does with a plus is simply extend the range of the nominal grade (such as 67) upward a bit and then assign the plus if the coin really exists near the top of that extended range. I honestly can&#039;t see them breaking the &quot;plus range&quot; down into three distinct values <i>beyond</i> the existence of the 67 grade proper. No one can grade a coin to that level of accuracy.</p><p><br /></p><p>No need to be sarcastic.</p><p><br /></p><p>PS: some years ago PCGS experimented with a 100 point scale between MS60 and 70; e.g. a coin might grade a 633 or a 657. They ultimately concluded it just wasn&#039;t possible and they adopted the plus designation.[/QUOTE]</p><p><br /></p>
